CVE-2026-19843

A flaw was found in 389-ds-base. The Cockpit 389 Console's LDAP editor constructs an ldapsearch command by embedding an LDAP entry's distinguished name (DN) into a shell command string without proper escaping. An LDAP user with delegated privileges to create or rename directory entries could craft a malicious DN containing shell metacharacters. When a Cockpit administrator subsequently views the entry in the 389 Console, the embedded shell command executes with root privileges on the directory server host.

8.4 (High)
CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H
